Wearable Display Device for Presenter Bio-State Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Presenters face challenges in smoothly conducting presentations due to limitations in existing display devices, such as smart glasses, which are small in size and interruptive, making it difficult to provide continuous information without interruption, especially when dealing with unexpected events or tense situations.
Innovation Solution
A display device mountable on the body, equipped with a microphone for voice input matching, a controller for adjusting content output speed, and a display for both eyes, which provides additional information like time and remaining content details, and includes bio-signal detection for adjusting output based on the presenter's state, allowing for seamless presentation management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If smart glasses are used as a display device for presentations, then the presenter can have information available during the presentation, but the device is small in size and the information transfer is limited
Solution Approach 1:
The patent transitions from traditional 2D screen viewing to a head-mounted display that utilizes the third dimension (spatial positioning around the user's head). The display device wraps around the user's head with display panels positioned at different locations, creating a three-dimensional information space that provides comprehensive visual feedback without requiring a large physical device.
2Productivity
If the presenter needs to provide continuous explanation without interruption, then the presentation flow is maintained, but it becomes difficult to provide additional information or handle unexpected events
Solution Approach 1:
The head-mounted display provides continuous visual feedback to the presenter by displaying not only the current presentation content but also upcoming content, timing information, and navigation cues. This feedback loop allows the presenter to monitor the presentation progress and adapt to unexpected events without breaking the flow of explanation to the audience.
Solution Approach 2:
The display device shows upcoming presentation content and timing information in advance, allowing the presenter to mentally prepare for the next section or handle unexpected events before they occur during the actual presentation delivery.
3Ease of operation
If the presenter needs to monitor multiple types of information simultaneously, then comprehensive control is achieved, but the presenter becomes time-pressed and may omit important explanations
Solution Approach 1:
The display device segments information into different spatial zones and visual hierarchies around the user's head. Critical timing information, upcoming content, and navigation cues are positioned in different locations, allowing the presenter to quickly scan and prioritize information without being overwhelmed by a single crowded display area.

AI summary
A wearable electronic device including a wireless communication unit configured to be wirelessly connected to a projector for projecting a stored presentation onto a screen of an external device; a main body configured to be worn by a user; a microphone integrally connected to the main body; a sensing unit configured to detect a bio state of the user wearing the electronic device; a display unit configured to be attached to the main body; and a controller configured to match a voice information input through the microphone with a portion of the stored presentation, and to display a part of the stored presentation that follows the portion of the stored presentation matching the voice information input on the display unit, wherein the controller is further configured to change an output size of the part of the stored presentation that follows the portion of the stored presentation when the bio state indicates the user to be in a tense state.
